The Intersil ISL54065 device is a low ON-resistance, low
voltage, bi-directional, dual single-pole/double-throw (SPDT)
analog switch. It is designed to operate from a single +1.8V to
+6.5V supply and pass signals that swing up to 6.5V below
the positive supply rail. Targeted applications include battery
• Integrated Click and Pop Elimination Circuitry
• Click and Pop Circuitry Disable Pin
powered equipment that benefit from low r
(0.56Ω), low
ON
power consumption (8nA) and fast switching speeds
(t = 55ns, t = 18ns). The digital inputs are1.8V
logic-compatible up to a +3V supply. The ISL54065 also
features integrated circuitry to eliminate click and pop noise to
an audio speaker.

The ISL54065 is a committed dual single-pole/double-throw
(SPDT) that consist of two normally open (NO) and two
normally closed (NC) switches with independent logic control.
This configuration can be used as a dual 2-to-1 multiplexer.
